Insulators are crucial components of the HV overhead power lines. They serve two primary purposes: providing electrical insulation and offering mechanical support to the conductors [1–3]. In the network, one end of the insulator is linked to the live conductors, while the other end is attached...
AC electric power is widely used in industrial and residential applications. DC Current The flow of electric charge in only one direction is known as direct current (DC). DC is also referred to as “DC Current”. Although this is technically saying the same thing twice “Direct Current Curren...

What is a Shunt Capacitor? Acapacitor bankis very essential equipment of anelectrical power system. The power required to run all the electrical appliances is the load as useful power is active power. The active power is expressed in kW or MW. The maximum load connected to the electrical pow...
Book2020, High Power Impulse Magnetron Sputtering Jon Tomas Gudmundsson, Daniel Lundin Explore book 1.1.2 Electrical breakdown Electrical breakdown is an important phenomenon in discharge physics. Here we derive the breakdown voltage as a function of the product pL, where p is the working gas pressu...
Reliability of protection and apparatus selection of the electrical power systems depend on the correct and accurate calculation of short-circuit currents. The simulation of the electrical power systems is one of the methods that is used for the determination of the short-circuit currents. In this ...
No information is yet available on CXCR7, a newly defined CXCL12 receptor. Here we demonstrated that CXCR7 regulated interneuron migration autonomously, as well as nonautonomously through its expression in immature projection neurons. Migrating cortical interneurons coexpressed Cxcr4 and Cxcr7, and ...
A circuit is a closed loop of electricity, made of conducting components, a power source, and a load. Conductors provide pathways for the electricity to travel between components in the loop. A load is a device that makes use of the electricity in the circuit, such as a lamp. The compone...
This equation can be expressed differently to clarify its components. Hence, from the as the expression of voltage and current in the equation are instantaneous, the power is also instantaneous. The expressed power is time-varying. So, the power of acircuit elementis the product of voltage acro...
